Analysis of the significance and precautions of using ECG

　　With the improvement of living material levels, people do not shy away from all kinds of diets, causing physical harm. If they are not treated in time, it will seriously affect the life and health of patients. Therefore, it is very necessary to carry out the inspection of the electrocardiogram machine. Today, everyone in the EEG machine manufacturer understands the significance and precautions of using the electrocardiogram machine.

　　 1. What disease can be detected by electrocardiogram

　　 Electrocardiogram is a technique that uses an electrocardiograph to record patterns of changes in electrical activity produced by each cardiac cycle of the heart from the body surface. In each cardiac cycle, the heart is excited by the pacing point, atrium, and ventricle successively, accompanied by changes in bioelectricity, and various patterns of potential changes (ECG for short) are drawn from the body surface through an electrocardiograph. The electrocardiogram is an objective indicator of the occurrence, spread and recovery process of cardiac excitement.

The significance of 　　 ECG examination is that it is used to check various arrhythmias, ventricular atrial hypertrophy, myocardial infarction, arrhythmia, myocardial ischemia and other diseases. The tissues and body fluids around the heart can conduct electricity, so the human body can be seen as a volume conductor with a three-dimensional space of length, width and thickness. The heart is like a power source. The sum of countless changes in the action potential of myocardial cells can be transmitted and reflected to the body surface. There are potential differences between many points on the body surface, and there are also many points that are equal to each other without potential difference. To find out more ECG model, look for Gerui Tai.

　　 2. Precautions for ECG examination

　　 1. In terms of clothing, women should not wear bras, men should wear loose clothes, and be careful not to sweat too much, otherwise wet skin will easily cause short circuits between adjacent electrodes, and the measurement results will be inaccurate.

　　 2. No contact with radiation and radioactive materials. For example, try to avoid using mobile phones, microwave ovens, semiconductor radios, etc.

　　 3. The part of the skin that is in contact with the dynamic electrocardiograph should be free of local infection and maintain hygiene.

　　 4. Do not take a bath during ECG, it is best not to do vigorous exercise during the test, so as not to sweat to cause the instrument to fall off.
